In the next few days, Klein wasn't in a hurry to leave the catacombs.
Instead, he continued training Little Fox and Little Wind.
Klein knew very well that he didn't care about this little bit of time. After all, if he could raise the strength of Little Fox and Little Wind by a level, then it would save Klein a lot of time in the future.
Therefore, he had to spend this time.
Furthermore, in just a few days, Little Fox's speed and stamina had improved tremendously.
Previously, when Little Fox ran back and forth in the catacomb caverns, one could still see white light. Now, you could only hear sounds.
It was so fast that you couldn't even see a shadow!
This all meant that the training over the past few days had been very effective.
This also gave Klein a lot of confidence.
This meant that his training method was completely correct.
All Klein needed to do next was to continue using this training method.
